By applying mechanical pressure to the tendons, the direction of pull at the epicondylar attachments is altered and the force are both reduced and come from a different angle, allowing tissues to "rest". The C-shaped Clasp compresses the forearm musculature at its largest circumference below the elbow, without impairing blood flow.
